[fix](test) Fix decommission backend UT bucket count (#65202)
### What problem does this PR solve?
On branch-4.1, `DecommissionTest.testDecommissionBackend` creates
`test.tbl1` with `buckets 64`, but still verifies balance with
`totalReplicaNum = 1 * 2400`.
That makes the initial round-robin tablet distribution `[16, 16, 16,
16]` look unbalanced because `checkBalance()` computes the expected
average from 2400 replicas.
This PR aligns the branch-4.1 test with the master-side handling:
- disable `Config.max_bucket_num_per_partition` for this UT
- restore the DDL to `buckets 2400`
- keep `totalReplicaNum = 1 * 2400` unchanged
### Check List
- [x] `git diff --check HEAD~1..HEAD`
- [ ] `./run-fe-ut.sh --run
org.apache.doris.clone.DecommissionTest#testDecommissionBackend`
(blocked locally before Java UT:
`/Users/keshu/dudu/doris/thirdparty/installed/bin/protoc` is missing)
- [ ] `mvn test -Dcheckstyle.skip=true -DfailIfNoTests=false
-Dtest=org.apache.doris.clone.DecommissionTest#testDecommissionBackend`
(blocked locally before `fe-core`: generated `org.apache.doris.thrift`
classes are missing because generated sources cannot be produced without
`protoc`)
### Release note
None
